Explanation
Renewable energy sources are those that are replenished naturally on a human timescale.
- Biofuel (2): Derived from biomass (organic matter like plants and agricultural waste), which can be regrown or replenished relatively quickly.
- Hydropower (4): Utilizes the energy of flowing water, which is a continuous part of the Earth's solar-driven water cycle.
- Fossil fuels (1): Such as coal, petroleum, and natural gas, are non-renewable because they take millions of years to form and are depleted much faster than they are created.
- Uranium (3): Used in nuclear power plants. While nuclear energy is a low-carbon source, uranium is a finite mineral resource mined from the earth and does not replenish itself; therefore, it is classified as a non-renewable resource.
Thus, only 2 and 4 are renewable sources of energy.
